Replaced the Audionet electronics with Soulution 511+525. Went from CD based digital rig to a file based one using the Vivaldi Upsampler and Melco as a digital library.
Further to my comments on cabling you might also want to explore an external 10MHz master clock for the Scarlatti -- they're not that expensive and the effect is very positive -- more details on my experience here
Nice system. I don't see what you are using for digital cables in your DCS stack. Like many I've found that it's hard to beat Transparent Ref XL, costly but well worth it. Isee you have some third party footers and also damp the top plates - i got good results from Marigo footers under all my DCS gear and use Shakti stones on top. Anyway check out my detailed system description for more ideas on other tweaks to consider
